Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate processing, and more specifically to a light guide plate polishing device. Background Art

[0002] During the processing of the light guide plate, in order to ensure the light effect around the edges of the light guide plate, the light guide plate is usually polished. The polishing of the light guide plate will cause the problem of debris and foreign matter, which will adhere to the surface of the light guide plate and eventually form white spots on the screen. At present, the debris generated by the light guide plate during the polishing process is removed by an external vacuum cleaner. On the one hand, the adsorption capacity of the vacuum cleaner is limited, and the debris removal effect is not good. On the other hand, the light guide plate will generate a certain amount of static electricity due to the material itself and the polishing process. The debris generated during polishing will be adsorbed on the surface of the light guide plate through static electricity, and the vacuum cleaner cannot remove this part of the debris.

[0018] like Figures 1 to 3 As shown, a light guide plate polishing device includes a driving motor and a polishing head 1, an air cavity 101 is opened in the polishing head 1, a plurality of outlet air channels 102 connected to the air cavity 101 are opened at the bottom of the polishing head 1, a rotating shaft 2 is fixedly connected to the top of the polishing head 1, the output shaft of the driving motor is drivingly connected to the rotating shaft 2, an annular groove 103 connected to the air cavity 101 is opened at the top of the polishing head 1 around the rotating shaft 2, an annular slider 3 is slidably connected in the annular groove 103, an air inlet interface 301 connected to the air cavity 101 is opened on the annular slider 3, an air inlet pipe 4 is connected to the air inlet interface 301.

[0019] The air inlet pipe 4 is connected to a low-temperature plasma generator via an air pump.

[0020] The bottom of the polishing head 1 is provided with a chamfer 11 .

[0021] The air outlet of the outlet flow channel 102 is arranged at the chamfer 11 .

[0022] The outlet flow channel 102 is arranged inclined.

[0023] A filter screen 5 is provided at the connection between the outlet air passage 102 and the air cavity 101 .

[0025] Working principle:

[0026] The low-temperature plasma generator generates low-temperature plasma gas, which is transported to the air cavity 101 through the air pump and the air inlet pipe 4, and ejected from the polishing head 1 through the outlet flow channel 102 to remove the debris generated by polishing, complete the cleaning of the debris during the polishing process of the light guide plate, and keep the debris away from the polishing head 1. When the plasma passes through the surface of the light guide plate, the static electricity of the light guide plate and the debris can be neutralized, so that they reach an electrically neutral state, thereby eliminating the electrostatic adsorption of the light guide plate to the debris, making the debris easier to remove and improving the polishing effect.
